IIRC, it was 49.. There were 46, and then for a short time in the 1980s, 3 others ("The Three Little Pigs") were leased from another airline, thus totaling 49. They were returned, and we went back to 46.

No. GB is a tribute to Gary Baron who was a Chief Operating Officer for Southwest for many years. The reason that this aircraft was the first one to get winglets is simply because it was due to have its 5Y (five year) check and the winglet mod was added to the work package to minimize "down time".

I wanted to see how the D70 was working out for you...

I like it a LOT. I did some shooting with it last week and haven't had time to sort through everything. But so far, I like the results. The only bad thing is that I've been shooting in RAW mode and it takes longer for the pictures to load in Photoshop and the Nikon software is basically unusable on my laptop.
